WASH-BASIN.

SPECIFICATION forming part of Letters Patent No. 440,211, dated November 11, 1890.

Application filed June 27, 1890. Serial No. 366,945. (No model.)

To all whom it may concern:

Be it known that I, HENRY O. VVEEDEN, of Boston, in the county of Suffolk and State of Massachusetts,a citizen of the United States, have invented certain new and useful Improvements in Wash-Basins, of which the following is a specification.

My invention relates to that class of basins known as set-bowls, intended to be permanently set in place in an apartment in connection with suitable water-supply and waste pipes; and its object is to improve these structures, particularly with regard to the construction of the overflow and waste. Such bowls have heretofore been made with a recess in the rear, in which the dischargeorifice of the basin has been located. The overflow most commonly adopted heretofore has been a stand-pipe formed at the lower part to act as a plug or stopper to the discharge-orifice, and open at its upper part, so that when the basin is filled above a certain line it will overflow through the standpipe. It will be obvious that with a standpipe overflow so constructed it is necessary that it should be movdd when it is desired to empty the basin, and this feature of making the overflow stand-pipe a moving part has been found in practice to be disadvantageous.

The object of my improvement is to provide a bowl wherein the overflow-pipe shall be a siphon integrally and immovably a portion of the bowl-wall, so that the whole can be constructed of a single integral piece of earthenware, that being the material now preferred for such devices.

In the accompanying drawings, Figure 1 represents in top plan, and Fig. 2 in vertical section, a bowl embodying my present improvement, which I will now proceed to describe.

The main portion A of the bowl may be made square or oval, as desired. In the cen ter of'the rear wall is provided the recess B, at the bottom of which is located the dis charge-orifice O. In the recessed portion of the wall of the bowl I construct a siphon formed overflow-passage D E, the short leg I) of which communicates with the bowl,

preferably at a point d, at or near its bottom level. The long leg E of the siphon discharges into the outlet portion F of the bowl. The orifice C is adapted and intended to be closed by means of a basin-plug H of ordinary construction. For the convenient reception of the plug, and also to make a convenient union with the discharge-pipe leading from the bowl-outlet, a shell I may be inserted in the outlet F, as shown. The upper portion of this shell receives the plug 11, and the shell is slotted, as at z' i, so that water discharged from the siphon D E may pass oif, even though the plug H be seated.

It will be seen that the device above described may be constructed of a single integral piece of earthenware, that it has no moving parts, and consequently that it is entirely free from the liability to derangement that always exists in these devices when moving parts are employed.

The discharge-pipe G of the bowl is provided with a trap J, preferably of the S form, as shown, to cut off the passage of noxious vapors from the soil-pipe. From some point in the outlet above this trap I lead up to a point above the bend of the siphon-overflow an air-pipe K. This air-pipe serves to prevent the apparatus from becoming airbound, which might be the case if the outlet were omitted.

The operation of the device is very simple. If the discharge-orifice be closed by the plug, water may be admitted into and retained by the bowl until it reaches the height of the bend of the siphon overflow-pipe D E, thus enabling an ample depth of water to be had in the bowl when in use. At the same time, should water he allowed to enter the bowl to a greater height, the siphon action of the overflow is started, and the contents are thus removed rapidly and effectually.

I make no claim, broadly, to the idea of a siphon-formed overflowpipe, as such is not new with me.
